Product description Cressi Interface Leonardo/Giotto

The new CRESSI RGBM algorithm, developed by Bruce Wienke, has been adapted by Cressi for safe decompression computations in multi-day repetitive dives.

Tissues: 9 with saturation hemi-phases between 2.5 and 480 minutes;

”Dive” program: Full processing of dive data, even with decompression (if any), for any air or hyper-oxygenated mixture (Nitrox) dive.

Full setting of FO2 (percentage of the oxygen) and PO2 (partial oxygen pressure) parameters: PO2 may be set between 1.2 bar and 1.6 bar, FO2 between 21% and 50%.

A Nitrox dive may be carried out after an air dive (even with desaturation in progress).

Possibility of Deco (decompressive computations) or Gage program setting (depth gauge and timer).

Deep Stop can be enabled or disabled.

Large display with ”PCD System” for perfect understanding and readability of values.

Replaceable display protective cover.

Battery replacement can be carried out by the user.

Planning: Scrolling of the safety curve.

Unit of measure change from the metric system (meters and °C) to the feet system (ft- °F) by the user.

Sound and visual alarm systems.

CNS oxygen toxicity graphic indicator.

Backlit display.

Built-in calendar and clock.

Logbook (70 hours or 60 dives) including dive profile.

Dive history.

The instrument may be fully reset, in case of renting.

PC/Mac interface with simulator and dive profile (optional).

Cressi interface


Excellent product, used with Computer Leonardo, works with others, its price is very economical, works with other software programs such as Subsurface to download the dives. Very fast shipping

Ok with windows 10


Cressi Software with Windows 10, 64-bit, build 1703 works great. The software I had installed first, otherwise the interface was not recognized. If the software is running and you close to the interface, the blue LED and the yellow LED flashes every now on. Then turn on the dive computer, switch to PC-Link and place on the interface. The software instantly displays the connection and reads the serial number and the type of dive computer from. The interface has been at best for me in Germany Diveinn. For all retailers in Germany, the interface is more expensive. I can only recommend combining 10 Cressi Giotto with this interface and Windows.

As expected


Quick delivery and the Cressi interface was installed Automatically as soon as I connected it.



It is useful to save your dive, easy to use but it is pricy

Worked perfectly


I received the item promptly across continents, and can confirm it worked perfectly with my Mac even with the latest macOS Sierra. The Cressi provided software is a bit strange (dives disappeared once I restarted the software), but I used a free source software called Subsurface and had no problems.



Everything in order, punctual delivery.
